定义PROCEDURE P1 ( P_Asset_Type IN varchar2,P_Asset_SubType IN varchar2,P_OrderIds IN varchar2)。
需要根据传入参数动态查询,动态生成cursor或者动态执行SQL的DML操作。
1.简单的查询
SELECT ABC from TableA where ORDER_ID IN ( P_OrderIds) ;
2. 动态生成cursor
定义游标和变量:
type v_cursor is ref cursor;
C1 v_cursor; v_command varchar2(2000);
v_command := ''SELECT ABC from TableA where ORDER_ID IN ( '' ||P_OrderIds|| '' ) '';
OPEN C1 for v_command;
3.动态DML操作
v_command2 := ''UPDATE TableA
SET ASSET_TYPE_CD = ''''''||P_Asset_Type||'''''',''
||''ASSET_SUBTYPE_CD = ''''''||P_Asset_SubType||''''''''
||''WHERE ORDER_ID IN ( ''||P_OrderIds||'' ) '';
execute immediate v_command2;(动态sql)

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
